difference is in the hanging rack 3. Fig. 6 illustrates the breakdown
structure of the
hanging rack 3; in this embodiment, the hanging rack 3 is not fixed with
respect to the
housing, but movable up and down with respect to the housing; the sawtooth
blade
13
CA 02827135 2013-09-18
rack 321 can be movable up and down with respect to the housing; the sawtooth
blade
rack 321 is a fixation component for the sawtooth blade 32.
A self-locking device is disposed on the hanging rack 3, the self-locking
device
includes a pushing block 80, a limited post 71 and control block 72, there are
four
pushing blocks 80, which are laterally coupled to the sawtooth blade rack 321
of the
hanging rack 3 in sliding way; the limited post 71 is fixed below the tray 37,
the
limited post 71 is extended down and vertical to the laterally moving path of
the
pushing block 80; the control block 72 is fixed to the housing; in the depress
path of
the hanging rack and the entirety of the sawtooth blade rack 321 and the tray
37, the
pushing block 80 is laterally pushed.
Fig. 7 is the side view of the first state of the hanging rack of the Fig. 6;
Fig. 8 is the
side view of the second state of the hanging rack of the Fig. 6. the two
drawings
illustrate the working state of the second embodiment.
Fig. 7 is the default state of the whole device, the tray 37 and the sawthooth
blade
rack 321 are not depressed, the control block 72 is not contacted with the
pushing
block 80 of the sawthooth blade rack 321, making the limiting hole 83 of the
pushing
block 80 and the limited post 71 of the tray 37 mismatched. As the limited
post 71
moves downward, the tray 37 is stopped to be subsided. When the entirety of
the tray
37 and the sawthooth blade rack 321 are not under the depress, that is to say
when the
ingredient box is not positioned right, the tray 37 can not move relative to
the
sawthooth blade rack 321, the sawteeth blade 32 will not be extended upward
from
the bottom of the tray 37, it prevents lying and ensur the safety of usage and
the liable
of the movable component of the device.
As figured in the Fig. 8, when the ingredient box is placed on the tray 37,
the tray 37
and the sawthooth blade rack 321 are entirely subsided until the control block
72
contacts with the pushing block 80, making the pushing block 80 moving
laterally.
Then the limiting hole 83 of the pushing block 80 reaches to a certain
position, and
the limited post 71 of the tray 37 is freely passing through the limiting hole
83. Fig. 8
14
CA 02827135 2013-09-18
defines an unlock position that the tray 37 can move up and down freely
relative to
the sawthooth blade rack 321, so that the sawtooth blade 32 can be extended
upward
relative to the tray 37 to work out. Only if the whole device situated in the
unlock
position, the tray 37 can move up and down freely relative to the sawthooth
blade rack
321 to work out. Otherwise, the tray 37 is fixed relative to the sawthooth
blade rack
321 and the sawteeth blade 32 can not be extended out.
Fig. 9 illustrates the detailed relative position of the pushing block 80 and
the limited
post 71 of the Fig. 7, showing the status that the limited post 71 is limited
by the
pushing block 80 downwards. The limiting hole 83 of the pushing block 80 is
